Sea to Summit Triathlon - July 25, 2026
The Sea to Summit Triathlon combines core triathlon disciplines with elements of an adventure race. The course requires athletes, assisted by a support designate or porter, to complete a 1.2 mile swim, a 95 mile bike, and a final run that continues with a climb to the summit of Mount Washington, the tallest mountain in the Northeastern United States.
Entry is limited by qualifying standards for individuals. Required is completion of a full 140.6 triathlon or a 70.3 distance triathlon after January 1, 2021, with finish times faster than 14:15 for 140.6 or 6:15 for 70.3. Racers who competed in Sea to Summit from 2015 to 2025 and finished within the race time limit are prequalified. Athletes who have qualified for Ironman World Championships in the past ten years or who hold a current or former professional card are also prequalified. Athletes must be 18 years of age or older. Qualification rules for relay teams differ from individual requirements.
The event is presented by New England Endurance Events and is based at Spring Hill Recreation Area in South Berwick, Maine. Athletes have come from across the United States and internationally. Habitat for Humanity is listed as the event charity partner. Visit the organization's website for the most recent information.
